IMPROVEMENT IN FASTENERS FOR MEETING-RAILS OFSASHES.

Specification forming part of Letters Patent No. 126,754, dated May 14,1872.

To all whom it may concern:

Be it known that I, WILLIAM E.-SPARKS, of New Haven, in the county ofNew Haven and State of Connnecticut, have invented a new Improvement inSash-Fasteners and I do hereby declare the following, when taken inconnection with the accompanying drawing and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawing constitutes part of this specification, andrepresents in- Figure 1, an end view Fig. 2, a top view of the same;Fig. 3, an underside view of the same looking up; and in Figs. 4, 5, and6, de-

tached parts to illustrate the construction.

This invention relates to an improvement in that class of sash-fastenerswhich are arranged upon the meeting-rails of window-sashes to secure theupper and lower sash in their closed position, the object being aconstruction which will require little more labor than the process ofcasting,.thereby producing a very cheap but good fastener; and theinvention consists in a chambered base having an opening directlythrough top for the insertion and bearing of the lever, combined withthe lever, constructed with a downward-proj ectin g stud with oneormorelateral projections therefronnwhich, when set into the said baseor plate -the opening formed with notches for the admission of the saidprojections--the said stud taking its bearing in the said opening andturned to its working position-the said projections pass beneath thesaid plate and thus secure the lever to the plate; and coinbi nedwith aspring, which, bearing against the flat side of the said stud, retainsit in the position indicated by such flat side, either as locking orloosening the sash.

A is the plate or base, which is chambered (see Figs. 4 and 6,) thediameter of the stud at the base corresponding to the opening B in theplate, forms a bearing upon which the lever may be turned. On this stud,and below the base a distance equal to the thickness of the plate, Iform two projections, a b, in position corresponding to the two notchesa I) in the plate, when the said lever is at some point out of itsnatural path-that is, substantially as seen in Figs. 4: and 5-the leverturned back for insertion. The projections pass freely through thenotches, and the leversets into its bearing in the plate, and is thenturned to the position seen in Fig. 3, the projections passing beneaththe plate prevent the removal of the lever. In that position the springF is inserted, two sides of the lever being flattened, as seen in Figs 3and 4, for the bearing of the spring. The spring is supported at eitherend and the lever is held in either position by the said spring yieldingfor the turning of the lever to the right, which, when so turned, isheld in that position by the spring, as denoted in broken lines, Fig. 3.The projections to I) serve also to prevent the turning of the lever toofar-that is to say, the projection a prevents the turning of the leverto the left and the projection b prevents turning too far to the right,whereby the accidental removal of the lever is avoided. To moreperfectly provide against such accidental removal Iform a stop, n, uponthe inside of the case, back of the spring, to prevent the depression ofthe spring by the said projections should they be turned into contact. Ialso form another projection, t,'on the opposite side of the case,against which the projection a strikes when thrown out, as seen in Fig.3.

While two projections and corresponding notches are preferable, onenotch and projection may alone accomplish the object, but not soperfectly as two or more. The keeper may be any of the knownconstructions.

I claim as my invention- 1. A sashfastener, consisting of the plate Aand lever C, when the said plate A is constructed with anopenin g, B,and one or more notches,

a b, in the said opening, and the said lever, with a stud, D, providedwith projections corre sponding to the said opening and notches in 3. Incombination with the subject-matter of the said plate, the saidprojection or projecthe second clause of claim, I claim the stops attions to pass beneath the said plate when the t, one or both, beneaththe plate, substantially lever is set into position substantially asdeas and for the purpose specified.

2. In combination with the subj ect-mattei' of the first clause ofclaim, I claim the spring I, Witnesses:

the stud D being constructed to take a bearing G. W. BURDETT, on thesaid spring, in the manner described. CHAS. L. BALDWIN.
